Molybdenum Knuckles

Taken all the way down to base materials, one Molybdenum Knuckles is 2 crafting steps deep and needs 3 intermediates — Durium Nugget ×2, Molybdenum Ingot ×2 and Zelkova Lumber ×1 — which resolve to 5 distinct raw materials totalling 24 units, plus 33 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,021 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 15 Fire Crystal, 13 Wind Crystal and 5 Earth Crystal.

The chain crosses three disciplines — Blacksmith to Lv 68, Carpenter to Lv 68 and Goldsmith to Lv 64 — so no single class can finish it unaided.

All 5 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Durium Nugget has the widest use: 142 recipes call for it, spanning seven of the eight crafting classes.
